"A medicine is effective for 80% of patients. The table shows 30 randomly generated numbers from 0 to 999. Use the table to estimate the probability of the event."
6. The medicine is effective on each of three patients.
7. The medicine is effective on fewer than two of the next three patients.
Answer:
1/2 & 1/10
Step-by-step explanation:
Each of three:
15 outcomes have all three digits 1 through 8
So, 15/30 which is 1/2
Fewer than 2 is one or none being effective, i.e one or no digits are 1 through 8
There are only three such outcomes
So, 3/30 = 1/10

Donald is participating in a fun run to raise money for the West Side Children's Hospital. The run is held at Donald's high school track. The more laps Donald runs around the track, the more money he raises for the hospital.
There is a proportional relationship between the number of laps Donald runs, x, and the amount of money he raises for the hospital (in dollars), y.
x (laps) y (dollars)

Answer:
I'm not totally sure what its asking, but here's a radio- 1:5
Answer:
y = x(5)
Step-by-step explanation:
Examples that prove this to be true are:
1(5) = y
y = 5$
2(5) = y
y = 10$
The reason this is correct is that it follows the same pattern on the graph.

Would someone mind helping me? 20 points for a great and correct answer!
Thank you!
Answer:
Step-by-step explanation:
So basically you have to do the Pythagorean Theorem here.
Which is = a^2 + b^2 = c^2
So you'll put 35 in 'a' and 84 in 'b'
It'll be like this = 35^2 + 84^2 = c^2
So here, we are looking for 'c'
And 'c' is the hypotenuse
So,
Step 1: 35^2 + 84^2 = c^2
Step 2: You will use the exponents (but not for c)
= 1225 + 7056 = c^2
Step 3: You will now add 1225 + 7056 = 8281
Step 4: Now, square root 8281√8281 = 91
91 = c
Hope this helps! Please let me know if you get this correct!

A bag holds 5 red marbles, 7 green marbles, and 4 yellow marbles. If marbles are not returned to thr bag afetr being drawn, what is the rpobability that the first marble will be red and the second marble will be yellow?
A. 1/4
B. 1/12
C. 3/16
D. 4/52
Answer:
1/12
Step-by-step explanation:
Total number of marbles = 5+7+4 = 16 marbles
Probability of picking a red marble = 5/16
Because the red marble is not returned back after being picked up, the total number of marbles is now 15.
Now,
Probability of picking a yellow marble = 4/15
The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12
Round 1.85 to 1 decimal place
Answer:
1.9
Step-by-step explanation:
1.85 is expressed to 2 decimal places. Since the '5' is ≥ 5, we round 1.85 UP to 1.9.

Ryan and Mariah are playing a game. Whoever wins a round gets 7 points. Whoever loses a round gets -3 points. Mariah lost the first two rounds. How many points does she have?
100 Points and Brainliest Award if you get this right! [Tricky]
Answer:
For one of them, it will be B=(4.5, 1.5). The sides would each be 3.54 long.
For the second, B=(1.5,5.5). Lines AB and CB are also going to be 3.54 long.
Step-by-step explanation:
My thought process was all over the place, to be honest with you. I drew out the points on some graph paper and found out the length of AC, which is 5. Then I thought I could use the law of sines since we know that the other two angles are both 45 degrees. Anyways, I got the lengths as 3.5. I was a bit off, but I found that out later. I thought of using a compass to try to see where a point would meet if there is a distance of 3.5, but I don't have a compass, so I went searching for online ones. I couldn't find one with a graph in it, so I used an online graphing system. From the beginning, I knew that it was probably going to be something .5, so I kept on trying to find a spot that had a length of 3.5 on both sides, and got really close, but they were still off. I checked where B was graphed, and it was a really long decimal, so I just put it to .5 on both the y and x and voila, I got 3.54 on both lines AB and CB. I, of course, checked my answers and found that the angle was in fact 90 degrees and I felt very pleased with myself. I did a simpler version for the other angle.
I hope this is correct! Please let me know, this was really fun anyways!
Julie runs a catering business. Last year she catered 212 dinner events and 148 lunch events. Which proportion could be used to determine, p, the percent of total events Julie catered that were dinner events?
Answer:
Step-by-step explanation:
the percent = # of dinner events/(total # of events)
= 212/(212 + 148)
= 212/360
= 0.5889

the unit digit of a 2 digit number is 5 more than the tens diget and the number itself is 3 times the sum of the digits. find the NUM
Answer:
27Step-by-step explanation:
Let the tenth digit is x and units digit is y.
We have the following equations:
y = x + 5(x + y)*3 = 10x + ySimplify the second equation:
3x + 3y = 10x + y2y = 7xSolve by substitution:
2(x + 5) = 7x2x + 10 = 7x7x - 2x = 105x = 10x = 2Find y:
y = 2 + 5y = 7The number is 27
Here the equations are if the digits be a and b
b=a+5--(1)3(a+b)=10a+b
3a+3b=10a+b7a=2bb=7/2a--(2)Equate both
7a/2=a+57a=2a+105a=10a=2And
b=2+5=7The number is 27

a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm
8.125/2 = 4.0625 x 192 = 780 cm
5/2 = 2.5 x 192 = 480 cm
Actual dimensions: 780 cm by 480 cm
Divide by 100 to convert to meters:
780/100 = 7.8 meters
480/100 = 4.8 meters
b: area of a triangle = 1/2 x base x height
area = 1/2 x 480 x 780 = 187,200 square cm
1/2 x 7.8 x 4.8 = 18.72 square meters
i did the dimensions in both cm’s and meters
Answer:
For A i would put 64 because its basically doing the total wing size divided by the number of sides it has.. And for B i havent thought of that yet..

Solve six and two sixths times one and one half.
A) Six and two twelfths
B) Eight and six twelfths
C) Nine and six twelfths
D) Ten and two twelfths
Answer:
C) 9 and 6/12
Step-by-step explanation:
The easiest way to do this would be to turn both of the mixed numbers into improper fractions, this makes 6 and two sixths into 6 x 6 +2= 38/6 and 1 and one half into 1 x 2 + 1 = 3/2. From there multiple the numerators together (38x3) and the denominators together (6x2) to get 114/12. To turn this into a mixed number again, divide 114 by 12 to get 9 with a remainder of 6 to get 9 and six twelfths

Does Brady have enough information to figure out the values of a and b? Explain your reasoning.
Answer:
According to the given attachment
L is a straight line and we know Sum of all angles formed on a straight line is 180° .
So,
➠ a + 90° + b = 180°
➠ a + b = 180° - 90°
➠ a + b = 90°
If angle a = angle b so we can easily find the value of a & b .
So, according to me " the given figure has not enough information to find out the value of a & b .
Please answer and hurry. Last one.
